unnecessary, being well known in the art to These propellers are of the usual type, and are driven by independent motors within the fuselage under the instant control of the operator, one propeller being adapted to push a and the other to pull, both propellers operating simultaneously.

By placing-the motors in the fuselage, wind resistance is cut down when the airplane is in flight. Also thus locating-the mo shown. These ailerons are operated by any suitable means whereby the airplane may be elevated or depressed.

Extending downwardly, below the lower wings 12, are fixed either rigidly or hingedly, thin abutments or fins 22 reaching transversely entirely across their under surfaces,

and presenting outer end edges, against which the lower ailerons 21 may be closely folded by mechanism under the control of the operator, thereby providing a pocket-like parachute of which the wings constitute the upper or cover member. These parachutes are of such considerable area as to fioatingly support the structure when so desired or in case of damage to the driving mechanism. The thin abutments 22 also act as stabilizing fins. Also when the rudders 13 are operated to turn the airplane, the rudders are in angular position with respect to the abutments and air or wind pockets are formed thereby thus enabling the airplane to make a turn more rapidly and positively.

The upper wings 11 may be provided with similar fins 22 for the same purpose. v

The descent of the airplane is aided by the actions of the stabilizing blades 15.

It is to be observed that the rudders 13 and fins 22 perform dual functions. The plane will always maintain its equilibrium and even keel due to the stabilizing effect of fins 22 and position of the rudders 13 Because my airplane is equally balanced throughout and because of the provisions therein of the front ailerons, rear propeller, and the absence of a tail, the airplane may be 'made to ascend safely from a comparatively small area; and by the inclusion of the elements'producing a parachute effect,'and the further inclusion of the stabilizing blades, the same may be made to descend within a comparatively small area.

Although the foregoing is briefly a description of the device in general, it will be understood that very considerable details have been omitted, all of which is regarded as :which the invention pertains.

It is further obvious that changes in the structure may be made-without sacrificing the 1 general spirit of the invention.

While I have shown and described a preferred form of embodiment of this invention I am well aware that other modifications may be made and I therefore desire a broad interpretation of the invention within the scope and spirit of the disclosure herein and V the claims appended hereto.

Having thus described the invention, what is claimed as new and desired to obtain by Letters Patent, is
